As others have said, just because some people have zero issues in the rain doesn't mean others don't. Some of the roads here in the NE get real slick just being wet. I mean I can "take off" from a stop like Granny Smith and still get spin. Last night came through a torrential downpour. I experimented at a stop light, and on green accelerated like a normal person (not racing and not trying to inch along) and a jump in the rear. Next light went to 4WD auto - made a difference. Maybe it's a placebo effect, but in inclement weather the 4WD auto makes me feel safer. I drove for almost a decade in my AWD 300 and never once had any issues with spin.
